UXIIIARY FORD' STARTER 'STVTCH AND SW'TCHLOPBATINGfMECHANSM.

f Applic'ationled AugustlZ,` 1926. 'Serial No. 128,718.

This invention-relates 1to 'auxiliary Ford y starter Iswitches 'andswitchoperating' mechanisms andfhasv as vits prime objectiitheprovision-01" a cliwicelot this kind to permit the chauieur'to assistthe" starter' in turning over 'the engine rb vcrankmg the sainewlnleoper- *ati'ng the starterswitch.

furtherobject is toic'onstruct a simple f and practical dev-ice ofthe4kind'described whiclri is adapte dtol cooperate with the" primary`starter* switch. l

iA" stillti'i'rther object is to prov-ide a comfpact'and substantialswitch which can be operated from the front ot the machine.

Other objects and advantages ot the device will be apparent from theaccompanying drawings and specification.

In the drawings- Figure 1 is a plan view of a Ford chassis and enginehaving 'this invention mounted thereon; the chassis and engine beingshown in dotted lines.

Figure 2 is a cross section of the chassis taken on the line 2 2 ofFigure 1.

Figure 3 is a plan view of the switch as connected with the starterswitch; the switch being' shown in dotted lines.

F igure d is a plan view of the switch independent ot the starter switchwith the cover removed.

Figure 5 is a side elevation ot the switch as shown in Figure 4.

Figure@ is a transverse section ot the. switch 'taken on the line 6 6 otFigure 3,

Figure 7 is a detail of the switch base and terminal posts.

Figure 8 is a detail of the contact plate and associated levers.

Figure 9 is a plan view of the auxiliary bracket and lever.

Figure 10 is a side elevation ot the said a xiliary bracket and lever.

In carrying out this invention I provide a hase 1 formed with a bracket2 and an integral side 3. Terminals 4i are insulated against and passedthru the said side 3 and are connected by means of conductors 5 with theconventional terminals (i ot' the late model Ford starter switch 7. Apivot pin 8 is rigidly secured in the base 1 and has a bracket 9carrying` a coil spring 10 nio-untyed thereon. The said bracket .9 isprei'erably` formed :trom ii'at sheet metal provided with ears l11pierced with apertures'12y thru which the pin 8 passes. The lowerear 11is formed'with an integral 'lever 13. The coil 'spring 10 has its onerend 14 securedinthe base 1 and its opposite end y15 in the upper :ear11 of the bracket 9. They forward end '16 ot the said bracket 9 carriesa conductor bar 17 which is adapted to engagethe ter-- ininals il torclosing the electric circuit thru said terminals rlie-2said.conductor`nar 1T is insulated against the bracket 9 `to prevent wallpossibilit-ies 'ot short'circiiitingthru"the said vbracket 9.

` rrco'ver'lS is provided with an integral 'arm 19 thru which a screw-2Ois passed to permit securrngthe-said cover to vthe base 1. A lscrew 21is `alsopassed lthru the cover 18 and is adapted to be screwed into thepivot pin 8. A slot 22 is out in the cover 18 in order to give treeaction to the lever 13. The bracket 2 is to be secured underneath 'the1door boards of the machine for which the device is adapted adjacent theStarter switch 7. The switch as shown is intended primarily to permitclosing' the elec tric circuit thru the starter 23 of the engine 24 fromthe front ot the machine. For this purpose it is necessary to provide aspecial bracket 26 which is secured to the automobile chassis 25. Alever 27 is pivotallj7 secured to the bracket The said lever 2 issubstantially triangular in form and is pivoted thru the base of saidtriangular torination to the said bracket 2G as described. The forwardend otl the ,lever 27 has a pole wire 2S secured thereto. The said wire28 p thru the bottom ot the radiator shell (not shown) and is formed atits tree end with a finger loop 29. The base of the said lever 2Tadjacent the pivot point ot said lever is pierced with an aperture 30 topermit securing a tie-wire 31 therein which is secured in the lever 13.

The switch as described is intended primarily 'for use upon the latermodel Fords in conjunction with the starter switch 7. In extremely coldweather, when the engine is stitiA so as to overload the starter 23. itis desirable at times to assist the said starter b v cranking while thestarter is endeavoring to turn over the crankshaft (not shown) ot theengine. In this respect it is necessarjY to close the circuit thru thestarter switch 7.

in operation the starter swich 7 is closed bv drawing out the pole wire2S which partially rotates the lever 27 on its pivot thereby drawing thelever 13 toward itself thru the medium of the wire 31. In thus drawingthe lever 13 toward the lever 27 the bracket 9 is turned upon its pivot8 so that the conductor bar 17 will engage the terminals 4' and thusclose the electric circuit thru said terminals. As soon as the wire 28is released the spring 10 turns the bracket 9 to its former positionthus breaking the electric circuit thru the said terminals 4.

While I have herein described a certain specific method of constructingand assembling the elements ot' my invention, it is understood same maybe varied in minor details, not departing from the spirit of myinvention as defined in the appended claims.

I claim:

l. In a switch of the kind described in combination with a conventionalforni of starter switch embodying conductors connected to the starterswitch terminals; a

. base formed with an integral side and a bracket for securing to theunderside of the starter switch; insulated terminals passed thru saidside connected to said conductors; a spring set bracket formedV with alever pivoted on said base; an insulated conductor bar secured to saidbracket for engaging said terminals passed thru said side; a bracketsecured to the chassis of the machine; a triangular lever pivoted onsaid bracket; a wire secured to said bracket; a wire secured to saidbracket lever and said triangular lever; and means secured to saidtrian-` gular lever extending at the front of the car for operating saidswitch.

2. In a device of the kind described adapt ed for use in connection witha late model starter switch embodying conductors mount-V ed on thestarter switch terminals; a base formed with a bracket for securing tosaid starter switch; terminals connected with said conductors mount-edon said base; an insulated conductor bar pivotally mounted on said basefor engaging the terminals mounted on said base; and iexible meansconnected to said conductor bar for operating the switch from the frontof the machine.

In testimony whereof` I affix my signature.
